Half-Saint I just noticed that this an AT board in an ATX case. Is this one of the few ATX cases with mounting holes for both form factors?

Correction, it was 2 minutes not 4 😉 Still horribly slow!
I just replaced the small heatsink with a Zalman CNPS6000-AlCu and added a 120cm fan (wired for 7V) in front of the case for some air circulation. It's currently sitting there idle at 60C. Not sure I like it that hot.
++++UPDATE++++
Replaced the Zalman heatsink with a stock Intel socket 370 cooler and some Arctic Silver 5. The fan is spinning at its slowest but the temperature doesn't go above 48C. I'll try the Zalman when the 2+ arrives.

The board has both AT and ATX power connectors. I had absolutely no problem mounting it in the case. I think the mounting holes are plain standard ATX.
😲 For real?
The PSU is usually no problem, there are adapters for that. But I was under the impression that, unless the case has AT mounting holes, an AT board will not mount in an ATX case.
What I don't understand is how I was able to passively cool a Pentium III 800MHz with the CNPS6000-Cu cooler but am unable to do so here. The idle temperature of that P3 was around 53C and 60-61C under load. On paper, the P3 has about double heat dissipation!
Its an AT/ATX motherboard. They were designed to work in either case with either style of power supply. They were common in 1997-99 when the market was transitioning from AT to ATX cases.

Should be much cooler with two 120s ventilating the case 😕 . My 2c ...
- The temp reading isn't real: Monitoring software not reading the K6-2 OK.
- The temp reading is real: Some heatsink clamping problem, overvolting.
Let the air flow!

Looks like one cap was in the way preventing the heatsink to make good contact with the heat spreader. I pulled out the copper version of CNPS6000 and cut off a small piece. Tomorrow I'm going to lap the heatsink and reinstall. Stay tuned for pictures and progress report 😀
I've found that the D and E revisions of that chipset, (you have an E) cannot cache memory past 128mb. So if you remove 2 of your dimms, I wouldn't be surprised if you gain a little more performance. If you want all of your 368mb cached, then you need to get a plus cpu. like this: http://www.ebay.com/itm/280652557202 it should run fine @ 6.0x100 and the + processors will cache 4gb of ram.
This guy seems to know his stuff: http://www.amd-k6.com/cacheable-ram-on-socket-7-platforms/
It is a mistake to think you can solve any major problems just with potatoes.
Oh, I have a K6-2+ 550 on the way 😀 I'm currently using 2x 256MB PC133 and it's bloody fast as it is. Especially with the 'new' hard drive installed.
The only version of HWMonitor Pro that will run on this PC is 1.07. All the others just give me the blue screen. Here are the idle temps:
TMPIN0: 31C
TMPIN1: 36C
TMPIN2: 48C
Prime95 won't run. Tells me I need a newer version of Windows. I installed the unofficial SP3 so that might be the reason.
Here's the modded heatsink:
Installed:
Try Speedfan, superb little program with compatibility all the way back to Win 9x. No bling bling and gets reasonably accurate temps.
Make sure the CPU heatsink doesn't phisycally touch and cooks any of those fine Sanyo caps.
Let the air flow!

Thanks for the tips. I'm not too worried about the caps. The cap closest to the heatsink is still not touching it. I'll be replacing the CPU as soon as the replacement gets here. A K6-2+ should be generating less heat.

From version ~26.x onwards Prime95 wouldn't work on ancient relics. To torture retrocomps please use 25.11.

I don't get it why they say it'll work on Win 9x when in fact it doesn't? Same goes for CPUID and HWMonitor...
That AMD K6-2+ 550 finally arrived yesterday. Can't wait to test it! 😀
